Title: Dispenser for flanged head stud-clips for fixing car door liner - has offset gravity feed tubes with hand operated slide gate
IPC: B25C5/00
Filed: 1974-03-14
Abstract: The semi-auto stud-clip dispenser for use in fixing automobile door lining panels etc., constitutes a gravity feed tube in two parallel contiguous but offset lengths interposed by a transversely sliding and hand actuated gate (20): the upper tube (12) serving as a magazine and the gate by reciprocal sliding motions authorising the passage of studs (11) one by one into the lower passage (19). A hand clenching action effects convergence of the slide (20) support body (2) towards the lower passage (19) body (3), thus, effecting the slide: counter springing (6) effecting recoil. The base of the slide body bears a lower slide (36) with inclined ramp (38): this latter causing a forked stud gate (26, 28) to rise and disengage leaving the stud held but projecting for presentation to the workpiece.

Title: IC engine cam-shaft - opens inlet valves at TDC and closes valves twenty seven degrees after BDC
IPC: F01L1/08
Filed: 1974-05-16
Abstract: The camshaft controls operation of the engine inlet valves, opening them at the top dead centre positions of the respective pistons, and shutting them 27 deg. after bottom dead centre. The valves can remain open for 207 deg. of crankshaft rotation. The design avoids the mixture being blown back into the inlet manifold, as would happen if the valves opened before top dead centre on a conventional engine, and also any of it passing out with the exhaust gases unburnt.
Patent FR-2235440-A1 (FR)
Title: Ultrasonic intruder detector system - has central unit which controls parallel emitters and has receivers triggering alarm
IPC: G01S15/50
Filed: 1974-06-18
Abstract: The central unit feeds the required frequency a.c. to the emitters of ultrasonic radiation and at the same time supplies the receivers which modulate the d.c. current with changes in the detected ultrasonic reflection. The latter are due to Doppler effect produced by the presence of an intruder within the field of emitted ultrasonic waves, and this in turn results in the generation of a warning signal. The receivers comprise a circuit for a.c. rectification connected as a supply for the strobing circuit, and the changes in the d.c. current are sensed by the central unit for tripping the alarm.

Title: Solids sepd. from liquids by decantation - with spiral flow between successive stages, using small surface area
Inventor: CUVILLIER ROGER
IPC: B01D21/00
Filed: 1974-08-02
Abstract: Solid particles are septd. from a liq., in which they are suspended, the particles being denser than the liq. consists of charging the suspension to the centre of a space already filled with liq. and preventing the mass of liq. from being displaced radially, so that the particles are decanted vertically. A superficial layer of liq. is displaced horizontally so that each unit of vol. of this layer follows a spiral path from the centre to the periphery where it is discharged. The solid particles are discharged from the bottom of the space. The appts. for carrying out the process consists of a vessel with a central feed, bottom discharge, and a number of vertical coaxial partitions forming anular compartments. Each partition has an indentation in its upper edge and the indentations in two adjacent partitions are diametrically opposite to one another. The vessel may be cylindrical with a conical bottom, or conical. Alternatively, there may be a spiral partition and there may be radial partitions in the spiral path so formed, and the heights of the partitions may be adjustable. The sepn. is made over a very small surfae, compared with existing decantation systems, which use several units, of very large surface, and rakes. The appts. is therefore cheaper to construct and occupies less space than existing appts.

Title: Aiming system for gun firing at moving targets - computes firearm azimuth and elevation rotations separately
Inventor: FAISANDIER JACQUES
IPC: F41G5/06
Filed: 1974-09-30
Abstract: The pivoted firearm on a base is moved so that it is compensated for interception, factors for target speed, average projectile speed and vector angles between target and projectile velocity. The overall correction is resolved into correction for rotation about a vertical axis and correction for elevation. Successive corrections are computed separately for these two rotations. The increments of the components of the overall correction are computed separately in relation to the increase of the component of the two successive rotating movements. Both increments evaluated in this manner are used separately for the azimuthal and elevation correction of the firearm. The input factors for the computer reproduce the increments as electrical analogue magnitudes which are fed into two electric motors for producing the two separate rotations of the firearm.

Title: Continuously extruding foam filled thermoplastics tube - using divided flow with expanding agent supplied to inner region only
IPC: B29C48/09
Filed: 1974-10-08
Abstract: A method of making hollow strip or tube of compact plastics possessing a foam core is as follows: the molten thermoplastics is fed into a tubular duct which is further sub-divided into an outer annulus and a central pipe; the thermoplastics flowing through the outer annulus constitutes the compact outer sheath or tube, while the same material flowing through the central pipe receives an injection of expanding agent, causing it to produce a foam core; the two streams then re-unite at a calibrating unit. Pref., the appts. is fed from an extruder which may be either coaxial or inclined to the axis of the appts. By using a single material and sub-dividing the streams during the foaming operation, a cellular structure in the external sheath is avoided and a smooth external skin results.

Title: Continuous casting using centrifugal force - where photoelectric cell and comparator control rotational speed of melt and ingot quality
Inventor: TRENTINI BERNARD
IPC: B22D11/14
Filed: 1975-06-04
Abstract: The melt is poured into the moulded at a point between the mould axis and the mould wall; and the central zone of the meniscus is scanned to obtain a signal corresp. with the radiation from that zone. The signal is fed to a comparator supplied with a standard reference value and any deviation is employed to adjust the rotational speed of the melt. The pref. appts. uses a photoelectric cell to feed the signal to a comparator, and a light beam may be employed to illuminate the central zone of the meniscus. The use of centrifugal force during the continuous casting of metals improves the quality of the ingot obtd. The slag and dross collects at the centre of the meniscus.

Patent FR-2358919-A1 (FR)
Title: High temp. reactor - uses radiant heat supplied to porous reactor tube
IPC: B01J19/12
Filed: 1976-07-23
Abstract: High temp. reactor e.g. for pyrolysis, decomposition and combustion reactions of organic and inorganic cpds. in which all the heat is supplied by radiation coupling comprises a reactor tube of porous refractory material capable of emitting radiant energy. Inert fluid is directed under press. through the porous tube wall to provide a protective blanket for the inside of the reactor tube. Reactants are directed in a predetermined path axially of the reactor tube and confined by the protective blanket within the central part of the tube. A heat shield directs radiant energy from an electric radiant energy source into the reactor tube to coincide with the path of the reactants. Since heat is supplied by radiation coupling the temp. of the reactant stream is independent of the temp. of the walls of the reactor tube. The tube therefore does not have to be made of material capable of withstanding the high temp. to which the reactant stream is subjected. The protective inert fluid blanket isolates the wall of the reactor tube from the reactant stream and prevents clogging by the accumulation of precipitates and deposits.
